ESD2700 Series

The EcoWater ESD2700 Series Water Softener is a single tank “cabinet” style, solid-state softener, making it a reliable and convenient system for your home.



  • Patented Electronics Digital Demand Module – Sophisticated, yet easy-to-use electronics capture historical usage patterns to predict future needs for precise regenerations.
  • Time Keeper – Permanent program memory with capacitor-backed time retention. Maintains time for at least 6 hours in case of power loss.
  • Multi-Wrap Fiberglass Reinforced Resin Tank – Durable tank liner will not deteriorate, rust, or corrode.
  • Self-Cleaning Distributors – Distributors exhibit excellent flow rates and are cleaned automatically by counter-current water pressure.
  • Positive-Action Brine Valve – Snap-together construction eliminates use of solvents that may contaminate water. Positive action helps prevent overfilling.
  • Automatic Bypass During Regeneration Means Continuous Water Usage
  • Barium and Radium Reduction, and Low Lead Content – This softener has been tested and certified by NSF International against NSF/ANSI Standard 44 for the reduction of Barium and Radium 226/228, hardness reduction and efficiency and NSF/ANSI 372 for low lead content.
  • Energy Efficient Power Supply – Simplifies installation, maintenance and reduces electrical hazards.

1Intermittent flow rate does not represent the maximum service flow rate used for determining the softener’s rated capacity and efficiency. Continuous operation at flow rates greater than the certified flow rate may affect capacity and efficiency performance. The validity of these flow rates is verified by NSF. 2Increased amounts of clear water iron can reduce softener’s efficiency. Refer to owner’s manual for details.
Wisconsin requires additional treatment if water supply contains greater than 5 ppm clear water iron. 3When operated at 35 psi water pressure. 4Maximum pressure for Canadian use is 7.0 Kg/cm2.
